The Union of Concerned Scientists (UCS) identifies several Texas coastal communities, including the Bolivar Peninsula, Sabine Pass, and Galveston, that face chronic flooding—defined as high tides flooding 10% or more of usable non-wetland area at least 26 times per year—by 2030 to 2100 depending on the sea-level rise scenario. The document argues that reducing global warming to around 1.8°C could save between 7 and 16 Texas communities from chronic flooding by the end of the century. To address these risks, UCS proposes three policy categories: ending risky coastal development, improving existing disaster frameworks like FEMA, and creating bold new policies for population relocation and infrastructure investment in safer areas.

  • Under an intermediate sea-level rise scenario, the Bolivar Peninsula and Sabine Pass are projected to experience chronic flooding by 2035. By 2100, a total of 17 Texas communities are expected to face this issue.
  • Under a high sea-level rise scenario, Galveston faces chronic flooding by 2030, and Port Arthur—home to the country's largest oil refinery—will face it by 2070. By 2060, over 60% of the Bolivar Peninsula and approximately 45% of Galveston will be flooded an average of twice per month.
  • Limiting global warming to approximately 1.8°C (the 'low' scenario) could prevent chronic flooding in three or more Texas communities by 2060 and between seven and 16 communities by the end of the century.
  • The document recommends three policy pillars: stopping risky coastal development (updating flood maps and building codes), enhancing existing frameworks (funding FEMA and disaster mitigation), and creating new policies for the relocation of populations from chronically flooded areas.
